Abstract
A gate drive circuit arranged to receive an input signal and provide an output signal to drive a gate of a transistor is presented. The gate drive circuit comprises a filter circuit arranged to attenuate a frequency band from the input signal when deriving the output signal from the input signal. The filter circuit contains programmable resistive elements, comprising: a first programmable resistive element arranged to adjust a low frequency gain and bandwidth of the gate drive circuit; a second programmable resistive element arranged to adjust a high frequency gain of the gate drive circuit; and a pair of programmable resistive elements arranged to adjust a driving gain of the gate drive circuit. A method of receiving an input signal and deriving an output signal from an input signal is also presented. The step of deriving an output signal comprises attenuating a frequency band from the input signal.
